To all whom it may concern:

Be it known that I, MARVIN B. VAN NESS, residing at Welsh, in theparish. of VCalcasieu and State of Louisiana,have invented certain newand useful Improvements in Pump Mechanism, of which the following is aspecilication. A. p A My' invention has for its object to provide animproved lconstruction ofn centrifugal pumping Ymechanism.-adapted fordeep or drawer wells, and more especially for use in connection withpits in which the rotary pumpinghead is held, and my said inventioncomprehends in* connection with the pump-` ing means an. im steel pit,whereby t located at a much possible with the ordinary types of squareits.

p My inventionin its more complete nature embodies an improvedconstruction of centrifu al or rotary pumping head, a sectional tubu arsupport for a sectional drive shaft connection therefor and means foralining the shaft sections, other details of construction and peculiarconstructionof parts also a coperative art of my invention, all of whichWill be ereinalter fully def scribed, specifically ointed out in theappended claims and i lustrated in the accompanying drawings, in which:

Figure l1, is a vertical section, parts being in Iperspective of myinvention. Fig. 2, is an en arged vertical section of the lower orrotary pumping head portion of the same, and showin the connection ofthe dee well tubing witi the bottom of the steell) pit Fig. 3, is anenlarged vertical section'of the upper end of the pump and illustratingthe adjustable ball bearing for the upper drive shaft section. Fig. 4,isa detail section of one of the iiange union couplings for the shaft.Fig. 5, is a horizontal section taken on the line 5 5 on Fig. 4. Fig.l6, is a horizontal section taken through the centrifugalpumpe pumpinghead can be lng head on the line 6-6 OfFig. 1. invention I use a steel-In carrymg out my greater depth than is' roved arrangement of pit 1having askeleton bottom 10 formed with a central opening 10'J1 to seatover the upper end of the deep well tubing 2, as best shown in F ig. 2,by reference to which it will be also noticed a the lower end of the pit1 which forms the bottom plate of thepump shell and which extendsentirely across the pit and formsa closure for the lower end of thepit.' .The

false bottom-3 is fitted inA steel bottom 3 has a central opening 30that "communicates with asuction pipe section 4 that extends somedistance down into the tubing 2, and carries a colla-r 4() at the upperend that is bolted tight on the'bottoin 3, and to cut off the tubingfrom discharging into the extreme lower end of the pit 1, a packing 5 isfitted onto the section 4, as clearly shown in the drawings.

lt should be here stated that in practice the pit 1 is of a smalldiameter, the said diameter depending on the capacit of pump desired andsize of the centrifugaf pumping head. ln practice, l have found forordinaryT 4uses a pit of 2 4 inches diameter as desirable, since a pitof this size can be readily sunk to .a great Vdenth through water and`quicksands,-it eing possible to go down one hundred feet or more. 'Theupper end of the pit 1 extends above ground level and has a dischargelateral 11, which, when the pump is used for flooding rice fields or otl12, as shown in Fig. The pit has a top ing 13a'througl1 which extendsthe pendent Athe upper-shaft section K Ashaped head 6O1`formed with aball-race 60b to receive the balls 63, that alsoengage the race 61a inan upper bearing section 61, that runs in the cup head 6()l1 thatcarries a clamp screw setting the section 61 on section 70, as bestshown in Fig. 3, which also clearly shows the bearing member 6i)securely clamped to the top plate 13 by the bolts 14-e14, and the brac'et bearing 15 also bolted to the head 13, through which the shaftsection 7() extends to receive the drive pulley 16. By making the lowerball bearin section cup-shaped, as shown, the same forms an oil receiverto provide for running the bearing surfaces in oil.

Between each union connection of the casingsections S is clamped a ilange or disk member 17 l'ormed in a boxing i7that l'orm guides 'for the shaft sections, said boxings serving to holdthe said shaft sections in perfect alinement,

The rotary or impelling pumping head may be of any well-knownconstruction.

From the foregoing taken in connection with the accompanying drawings,the complete construction, andthe advantages of my construction ofpumping mechanism will be readily apparent to those skilled in this lineof invention.

By reason of arranging the centrifugal pump at the bottom of a deep it,connected with a deep Well tubing, assiiown and described, a great headof Water can be taken care of and constantly since b having a continuousor annular discharge etween the pump rim and the pit, there can be noimairment to a free delivery of the water as ast as it is drawn throughthe suction tube. By incasing the`shaft' as shown and described, andproviding the supports therefor, as shown, it 1s kept in eri'ectalinement and (ust and may, if desired, be kept Hooded with oil itsentire length and the correlation of the several parts is such that theentire rigging can be conveniently` and economically put up.

the manner of operationA What l. claim isz.

-1. In a priming means oi the character described, the olloWing elementsin combination, a bottom closed pit whose lower end is adapted to titover a upper end of the pit being closed and provided with a lateraldischarge, a 4rotary pump horiaontallfj,T disposed in the bottom ol saidpit, saidfpump having an annular discharge in the; upper portionthereof, a drive shaft that extends down into the pit and carried withthe pumping head, and extends 'through the top oi the it,A a casing thatsurrounds the shaft insife the pit, a

suction pipe that extends from the Well tubing into the bottom of thepit'.

2. rihe combination with the pit closed lat the top and bottom having alateral discharge at the upper end and a central aperture at the bottomto receive the upper end of the well tubing; of a pump shell mounted onthe lower end of the pit having an annular upwardly directin iluiddischarge 'and a suction tube that 'its down into the tube, a rotaryumping head horizontally mounted in the s ell, a shaft connected to thepumping head that extends throu h the pit to a casing that surrounds thes ait, and a ball bearing and su port for the upper end of the shaftmountef on the upper end oi the tubing.
